In the data, we nd that the VVIX. has separate dynamics from the VIX, so that. uctuations in volatility of volatility are not. directly tied to movements in market volatility. The volatility-of-volatility risks are a signif-. icant risk factor which a ects the time-series and the cross-section of index and VIX option.

A Rogowski coil is a toroid of wire used to measure an alternating current i(t) through a cable encircled by the toroid. The above picture shows a coil encircling a current-carrying cable, with its output terminals v(t) connected to an integrator circuit, to obtain a voltage Vout(t) proportional to i(t) .t consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil.
